waiting for root message

hello all: im as newbie as it gets with this rooting,but very good at following instructions and very computer savy.I have a droid incredible with software 2.2,which Im trying to root.using unrevoked 3.21 I have followed all instructions to the tee,all goes well till the end,it says waiting for root,and stays that way for as long as you leave it. Ive tried 4 different computers all running win 7,one 64 bit,the other 3 are 32 bit,all with same result,(waiting for root) I first loaded the modified usb driver from unrevoked, it shows android bootloader interface good to go under android phone in device manager.I start the reflash program, made sure usb debugging was on made sure phone was connecting in charge mode,made sure unknown sources could be installed. I even tried installing htc sync,then uninstalling,because another site said drivers from htc sync were needed. nothing has got me by waiting for root. I have seen this same problem over and over on many different sites,but as of yet to see one fix, the procedure for unrevoked 3.21 seems very simple and straight forward, but every answer Ive seen to this problem,points back to original instructions,which Ive done over and over. any new ideas would be greatly appreciated. thanx in advance.
